Biogeochemistry and weathering in a forest catchment and an arable field in central Sweden

Abstract: Fluxes of base cations, nitrogen and phosphorus were investigated in a long‐term study at a forest site and a nearby arable site in central Sweden. At both sites soil mineralogy was reflected in the stream water concentrations, especially during base‐flow. Weathering rates for the major base cations and natrium (SBC + Na) in the forest soil calculated from empirical relationships and quartz distribution in the soil profile were 0.4 and 0.3 kmolc ha−1 year−1, respectively. Simulations using the PROFILE model of forest soil predicted a weathering rate of 0.6 kmolc ha−1 year−1 Net vegetation uptake of base cations was calculated to be larger, at 0.8 kmolc ha−1 year−1 In the soil of the arable site biogeochemical fluxes resulting from weathering and biomass removal were one order of magnitude faster. Budget calculations for the arable land indicated that a weathering rate of 7 kmolcha −1 year −1 was needed to keep the system in balance. Weathering of Mg was estimated to be equal to the amount applied as ferti...

Medical Geology in Europe

Abstract: Medical geology or earth and health has a long history in Europe. Also the newer development of medical geology has a firm base in Europe. Health problems associated with geologic material and geologic processes occur quite frequently in Europe. The problems associated with the geologic environment in Europe are generally chronic, caused by long-term, low-level exposures. Examples are exposure to trace elements such as fluorine, arsenic, radon, mineral dust and naturally occurring organic compounds in drinking water. The chapter provides the history of medical geology in Europe, many examples of these environmental health problems and a look into the future.
